representation of positive and negative number to binary 1 and 0 in matlab

• I have a column which has negative and positive values say
• volts = -5.2 -5.2 8.4 8.4 8.4 8.4 -5.2 5.2
• i have to represent positive number as 1 and negative number as 0. How should I write a statement for it in matlab??

result = volts > 0;

This will give you a logical result. If you need the result to be double, then simply

result = double(volts > 0);

You didn't specify what you wanted to happen to 0.

 >> volts = ((-5 + 10*(out0))*0.35);
 >> volts1 = ((-5 + 10*(out1))*1.4);
 >> voltsadd = volts + volts1;
 >> x(x>=0) = [1]
 >> x(x<=0) = [0]

I was trying the above example. Basically my target was to replace the negative numbers with 0 and positive with 1

now I have 2 results results of out0 has [1111000011110000] and out1 has [1111111111111111] (total 16 bits) how would I predict that final data value from out 1 is 1 if it has more number of 1 (i.e if the consistency of 1 is more) and final data value as 0 if its inconsistent)
